BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates to the medical field, and more particularly, tofacilitating communications between a patient, care-givers, visitors,and the like.

2. Description of the Related Art

Oftentimes, patients are unable, or have difficulty, speaking withcare-givers, visitors, and other personnel. This inability to speakclearly can make communications between the patient and othersdifficult. Typically, patients experience such speaking difficulties asa result of a particular medical treatment. Such is the case when apatient must be intubated or when the patient requires an inter-trachealtube. Patients also can experience difficulty speaking, not as theresult of a medical treatment, but as a direct result of an ailment,infirmity, or other medical condition. In any case, many situationsarise in which a patient experiences either a loss of the ability tospeak or difficulties in speaking.

Presently, when a patient who is unable to verbally communicate needs tocommunicate with care-givers, the patient uses a call button toeffectively page personnel. As a normal intercom response from a nursecannot verbally be answered by the patient, this generally requires thatthe nurse come to the room to find out what the patient needs. Inconsequence, the nurse must visit the patient. This can result inadditional work for the nurse as a second, and even third trip, may benecessary, but cannot be determined until after the nurse has visitedwith the patient.

Alternative communication methods can be used in the case where apatient who is unable to verbally communicate wants to communicate withother persons within the same room. The patient can be given a sheet ofpaper having printed thereon the letters of the alphabet. The patient isasked to point to the letters one by one in order to spell words. Thisspeech alternative, however, does have disadvantages. For example,detecting where one word ends and another word begins can be difficult.Consequently, as the patient points to the letters, the person with whomhe is trying to communicate may not be able to follow what the patientis trying to articulate. Further adding to the problem, the patient maylack manual dexterity as a result of a medical treatment or conditionand have difficulty pointing to desired letters. In an emergency, thiscan create a life-threatening situation.

Handwritten notes can provide another alternative to verbalcommunication. Some of the disadvantages associated with the use of aletter chart, however, also can apply to the use of handwritten notes.In fact, handwritten communications can require more manual dexteritythan merely pointing to a letter and, at best, are tediously slow.Another disadvantage is that passing notes amidst the large number ofcables, wires, monitors, tubes, and other medical equipment often provesdifficult. Moreover, while fumbling for pen and paper or passing a note,one can inadvertently disconnect a monitor or tube thereby endangeringthe patient.

Conventional healthcare monitoring equipment, for example of the varietyoften used within intensive care units, is often thought to preclude theneed for patients to call a nurse. Such equipment, however, can generateerroneous alerts and/or signals, must be reset from time to time, andmay not be able to respond to each emergency need of a patient. Still,patients can have other needs or reasons for calling a nurse other thanthose which are monitored by conventional monitoring equipment.

While some attempts have been made to develop more effective patientcommunication systems, such systems have yet to adequately address theneeds of patients lacking the ability to communicate verbally. Moreover,many systems do not facilitate communications between the patient andother persons in the same room, various hospital service personnel, orwith visitors in remote locations whether or not they have the abilityto speak.

DESCRIPTION OF THE INVENTION

The invention disclosed herein provides a method and system forfacilitating communications between a patient, care-givers, and visitorsin cases where the patient may be unable or unwilling to speak. Inparticular, the invention can facilitate communications between apatient and one or more visitors within the patient's room.Additionally, using the invention, patients can communicate withvisitors who are located at a visitor center which is remotely locatedfrom the patient's room. The present invention enables patients tocommunicate with care-givers located throughout a care-taking facility,such as a hospital, assisted living facility, and the like. Datarelating to the administration and delivery of different care-giverservices, including but not limited to, response times to patientrequests, can be logged and tracked. Accordingly, the invention canprovide various reporting functions detailing the quality of serviceprovided by the care-taking facility and staff. The present inventioncan be used within any of a variety of care-giving facilities such ashospitals, nursing homes, assisted living facilities. Particular aspectsof the present invention can be used within the home as well.

The present invention can facilitate communications between patients,care-givers, and visitors. The communications can be typed textmessages, pre-programmed text messages, pre-programmed visual messagesincluding visual identifiers such as icons, colors, symbols, or otheralphanumeric characters corresponding to requests, responses, orservices, as well as audio and/or video, whether such communications arereal-time, near real-time, or are pre-recorded and stored for later use.The present invention further can provide a system for tracking thedelivery of various patient care services from a quality controlperspective. Still, the invention can increase the efficiency of patientservice delivery.

FIG. 1 is a schematic diagram illustrating an exemplary patientcommunication system in accordance with the inventive arrangements. Thepatient communication system can be used to communicatively link severalremote locations within a patient care center such as a hospital orother medical facility. As shown in FIG. 1, several computer systems,including a patient system 125, a nurse station computer system 140, anutrition center computer system 150, a visitor center computer system160, as well as hospital administration computer system 170, can becommunicatively linked through the computer communications network 200.Still, other locations within a given care-taking facility can becommunicatively linked if necessary and if suitably equipped.

A patient room 120 can include a patient system 125 having a patientcommunication center (PCC) 100, a video display 130, a patient computer135, and a patient door display 195, each of which can be operativelyconnected. The PCC 100 can be a keyboard data entry module configured sothat a patient can type or activate particular buttons on the PCC 100.The video display 130 can be a television, a computer monitor belongingto the computer system within the patient room 120, or another displaysuch as a flat panel display, a liquid crystal display, or any otherdisplay suitable for displaying text and/or images. Moreover, thepatient system 125 can include various peripherals such as a microphone,a camera, and headphones or speakers to facilitate communications withother similarly equipped computers connected to the computercommunications network 200. Notably, the aforementioned peripherals canbe located in close proximity to the patient. In one embodiment of thepresent invention, the microphone, speakers, and camera can be disposedwithin the PCC 100. Still, these components can be individual componentsor can be included within the video display depending upon the physicaldimensions and layout of the patient room 120.

The patient door display 195 can be a video monitor, a lighted sign, oranother visual display capable of displaying images. The patient doordisplay 195 can be located inside and/or outside of the patient's room120. For example, the patient door display 195 can be placed above, on,or to either side of the door to patient room 120. Regardless, thepatient door display 195 can be configured to display particular iconsresponsive to activation of a corresponding button on the PCC 100. Theprimary function of the patient door display is to provide notice tocare-giver personnel that the patient has requested a particularservice. Once the service has been attended to, the icon displayed orilluminated on the patient door display 195 can be turned off.

Care-giver personnel can send and receive messages through computersystem 140 at the nurse station. Accordingly, care-giver personnel canrespond to patient requests and provide the patient with feedback.Notably, each of the computer systems 140-170 of FIG. 1 can bestandalone computer systems having an information processing capabilityas well as audio visual equipment such as speakers, headsets,microphones, and cameras.

Nutrition center personnel can interact with other personnel as well asthe patient through the nutrition center computer system 150 as shown.For example, through the patient communication system, the nutritioncenter staff can be provided with information indicating the patient'sname, room number, and any foods preferred or recommended by the patientor care-giver. Any other specific dietary requirements of the patientcan be entered into the a database or other data store at the time ofcheck-in. This information can be updated as required. For example, uponcheck-in or during treatment, information such as whether the patient ison a low sodium or low carbohydrate diet, whether the patient is avegetarian, and the like, can be determined. This information can beprovided in text form or can be indicated through one or more visualidentifiers such as color codes, alphanumeric codes, pictures, or icons.

From the nutrition center computer system 150, care-giver personnel canprovide the patient with menu information. This information can befiltered, and thereby individualized, according to the patient'sparticular dietary requirements. The patient can make electronic menuselections which can be transmitted to the nutrition center computersystem 150. Upon delivery of the food to the patient, a print-out of thepatient's food selections can be provided. Notably, a record of orderedfood, time stamp information corresponding to the time of order anddelivery can be stored for purposes of billing and tracking nutritioncenter performance. The data further can be used in connection withexisting inventory systems to determine when new food should be ordered,that food has expired, or to determine pricing of products.

Visitors can interact with the patient through the visitor centercomputer 160 as shown without having to be in the patient's room. Usingthe audio visual equipment of the visitor computer system 160, a patientreceives realtime or near-realtime audio and/or video from the visitorcenter. Still, if the patient is unavailable, visitors can record audioand visual messages for a patient which can be recalled for listeningand viewing at a later time. For example, if the patient is sleeping orexperiencing a particularly difficult day, the patient can view orlisten to the messages at a more suitable time.

Although some patients are not allowed to have visitors, or the visitorsare limited to only immediate family members, the presence of certainpeople can stimulate recovery of the patient and provide emotionalsupport to the visitors. Consequently, interactions through the visitorcenter can provide more meaningful communications to the patient simplybecause the patient knows that the visitor is close. The visitor centeralso accommodates visitors having a need to be close to the patient.

In any case, although the patient can view a visitor from the visitorcenter, the patient can choose whether to activate the camera within thepatient's own room. In addition, the patient can specify one or morelists of allowable visitors in addition to the parameters of each visit.For example, a patient may be willing to participate in a live videovisit with visitor A, but not an in-person visit. Similarly, if thepatient does not want any visitors, the patient can request that anyvisitors must record a message which the patient can view or listen toat a later time.

The administration center computer system 170 can be used to accessinformation, including, but not limited to patient requests, responsesfrom care-giver personnel, as well as the identity of responding staffand the responsible or “on-duty” staff member. Such identification isintended not only for efficiency and comfort for the patient, but alsoas a protection for patient and nursing staff against possible violentattacks. Notably, personal communications between patients and visitors,whether in the room or the visitor station cannot be accessed bycare-giver personnel through the administrative computer system 170.This information can be time and date stamped so that the informationcan be stored and tracked for quality assurance or other administrativepurposes. For example, the administrative center computer system 170 cangenerate reports indicating the timeliness of responses to patientrequests.

Computer system 180 can include one or more servers having one or moredata stores disposed therein, for example a network server for datastorage and retrieval or an application server. As previously mentioned,data can be cataloged according to the particular recipient, sender,time, date, message type, or content. For example, communicationsexchanged between the various stations and/or centers can be stored andtime-stamped for tracking and quality control purposes. As used herein,the term “data store” can include one or more individual data storeswhich can be communicatively linked and/or distributed across a computercommunications network.

The computer system 180 can be used to provide speech recognition andtext-to-speech processing capabilities, can store recorded audioprompts, as well as other multi-media information such as audio andvideo as previously mentioned including messages from the visitorcenter. In one embodiment of the invention, the computer system 180 canbe programmed with a language translation program for translating textfrom one language to another language. For example, upon admission tothe hospital, the patient can specify a desired or native language.Thus, text typed by a patient using the PCC 100 can be translated fromthe patient's specified language into English, and then be provided tothe destination node. The English language response from a care-giver orvisitor can, in turn, be translated to the patient's specified language.

FIG. 2A is a schematic diagram illustrating an exemplary PCC 100 inaccordance with the inventive arrangements of FIG. 1. As shown in FIG.2A, the PCC 100 can include a combination of different alphanumeric keysand keys labeled with appropriate icons corresponding to particularpre-programmed patient needs or requests. The pre-programmed patientneeds can be specified on a per patient basis thereby allowing eachpatient to specify one or more custom messages such as “please contactmy son at 123-4567”, or “please call my wife at “123-4567”. In oneembodiment, the pre-programmed messages can be programmed by thepatient. Still, a system administrator can program the messages when thepatient checks into the care-giving facility or at any time during thepatient's stay. Regardless of how the messages are programmed, the PCC100 can include icon labeled buttons having pre-programmed defaultmessages as well as patient specific messages.

The PCC 100 can include a standard alphanumeric QWERTY keyboard portion102 and a separate numeric portion 106. Using the keyboard portion 102and the numeric portion 106, the patient can type any of a variety ofmessages or enter different selections. One or more destination buttons104 can be provided. The destination buttons can be configured to routea particular message, whether typed or pre-programmed, to a particulardestination. One destination button 104 can be provided for eachlocation capable of communicating with the patient room 120. Forexample, a nutrition center button can route messages to the nutritioncenter and a visitor center button can route messages to the visitorcenter. Accordingly, responsive to activation of a destination button, amessage can be routed to the computer system corresponding to theactivated destination button 104. Despite the inclusion of one or moredestination buttons, the PCC 100 can be configured to route messages tothe nurse station by default.

The PCC 100 further can include a series of emergency buttons 108. Eachof the buttons can correspond to a particular pre-programmed emergency.Still, as mentioned, particular emergency buttons can be programmed on aper patient basis. Accordingly, some of the buttons can be patientand/or condition specific. Urgency buttons 110 can be used to indicatethe urgency of any non-emergency requests. For example, as shown, largercircles can indicate more urgent circumstances. Still, other visualidentifiers can be used such as colors, symbols, icons, pictures, andthe like. Buttons 114 can be speaker volume buttons for increasing ordecreasing the audio volume. The audio volume, for example from thevideo monitor or an intercom, can be increased or decreased responsiveto operation of the appropriate button. Button 116 can be a cancel callbutton allowing the patient to cancel a previous message or a requestfor a service. Buttons 112 can be additional pre-programmed or patientspecific function buttons which can be labeled with an iconcorresponding to the function of each button.

A list of potential function buttons has been included in Appendix A.Still, it should be appreciated that the list is for purposes ofillustration only. Accordingly, the invention is not so limited to theparticular functions listed or the particular physical layout of thebuttons or keys of the PCC 100. For example, in one embodiment for usewith children, the PCC 100 can include only large buttons havingdescriptive icons. In that case, an additional button can be includedfor requesting the child's parents. Depending upon the age of thepatient to be using the PCC 100, the QWERTY keyboard portion need not beincluded.

According to one aspect of the present invention, the PCC 100 can have adefault setting, which can be enabled or disabled, which monitors foractivation of too many, or more than a predetermined number of icons orbuttons at one time. The PCC 100 further can monitor for nonsensicalbutton combinations as may be defined within a system profile. If such acondition is detected, the PCC 100 can override the various activatedbuttons and/or icons and transmit an emergency signal indicating thatthe patient may be experiencing a health emergency or may not becoherent. A similar functionality can be included wherein text messagesare analyzed for spelling and or grammatical structure. If such amessage includes more than a predetermined number of errors, the PCC 100can send an emergency signal. The emergency functions described herein,however, also can be performed by a central server or computer system.

When possible, the icons on the PCC 100 keys can be commonlyrecognizable icons or other icons from the public domain to ensure thatpatients can intuitively operate the PCC 100. Regardless, the inventionis not limited to any particular set of icons. Rather, humorous icons,different symbols, pictures, colors, and/or alphanumeric identifiers canbe used. Preferably, the icon can provide the patient with an intuitiveindication of the function of the button or key. Each of the keys alsocan include a raised portion such as a brail letter, number, or symbolindicating the function or description of the button.

Patients can be provided with audible and visual feedback that a buttonhas been activated. Responsive to activation of a button, an audiblesound can be triggered. For example, if the “nurse” button is activated,a click can be generated or an audio prompt saying “nurse” can begenerated, for example from a recording or using text-to-speechtechnology. The audible signals provide notification to the patient thatthe correct icon has been activated. Visual notification can be providedby placing the icon or text corresponding to the activated button on thevideo monitor. The icon or text can remain on the video monitor untilthe particular patient need has been met. At that time, or when disabledby a care-giver, the icon can be removed from the patient's videodisplay.

In one embodiment of the invention, responsive to a first activation ofa button, an audio prompt identifying the activated button can beplayed. Upon a second consecutive activation, after the patient hasverified that the correct button has been selected, the functioncorresponding to the button can be activated, for example ringing thenurse station. Upon the second activation, the visual identifier can beplaced on the patient's video display informing the patient that his orher message has been sent.

The PCC 100 can be encased within a strong, lightweight, and waterproofhousing. An optional cover that can be wiped clean and sanitized can beincluded. For example, such a cover can be a disposable clear plasticprotective cover having an elastic band holding the cover on the PCC100. The PCC 100 can be attached or clipped to several types of holders,depending on the patient's needs or medical condition. For instance, ifthe patient has limited mobility, the PCC 100 can be attached to afreestanding arm extending over the patient's bed. The freestanding armcan be easily pushed out of the way allowing care-giver staff to performroutine or emergency procedures. The arm can be positioned so that thepatient can easily reach the icons, even while in hand restraints. Forexample, the arm can operate similar to a typical patient table in thatthe arm can include a base unit on wheels which allows the base to bemoved under the bed. The arm can be positioned to effectively raise orlower the PCC 100 as well as adjust the viewing angle of the PCC 100 toaccommodate the patient's position. When the patient acquires greatermobility, the PCC 100 can be attached to the hospital table, clipped tothe bed rail, or positioned in the patient's lap.

FIG. 2B is a schematic diagram illustrating another embodiment of thePCC 100 in accordance with the inventive arrangements disclosed herein.According to this embodiment, the PCC 100 can function as a standaloneunit. For example, in such an embodiment, the PCC 100 can include aprocessor 456 and memory 458 such as random access memory, read-onlymemory, and/or another type of fixed storage. The processor 456 caninclude and execute a speech recognition engine and a text-to-speechengine. Other information such as programmed messages or software basedsystems as previously discussed can be stored locally within the PCC 100as well. The PCC 100 further can include a power supply 460, forsupplying power to the various components of the PCC 100 as may berequired. The power supply 460 can be a conventional alternating currentpower supply which acquires electricity from a wall outlet, or can be aself-contained power supply, for example a rechargeable power supply.

As previously noted, the PCC 100 can include a display 462, whethersuitable for displaying text, images, and/or motion video. The displaycan be a small liquid crystal display or another portable display whichcan be readily incorporated into the PCC 100. The PCC 100 also caninclude a microphone 464, a camera 466, one or more audio jacks 468 suchas headphone outputs, and speakers 470. The PCC 100 can be configuredwith a suitable network interface 472 to communicate with othercomponents or stations within a care giving facility. The networkinterface 472 can be implemented as a wired interface or as a wirelessinterface.

Notably, the PCC 100 can include a radio transceiver 474 and/or awireless telephone 476. Accordingly, users can initiate communicationsto locations external to the network through which the PCC 100communicates with other stations. Notably, in addition to conventionalvoice communications, the PCC 100 can be programmed to dial numbers orcontact other parties via the wireless telephone 476 or radiotransceiver 474 and play programmed messages once a connection has beenestablished, for example, using text-to-speech technology or recordedmessages. For example, the PCC 100 can be configured to dial “911”service responsive to activation of one or more keys.

Though the present invention is not limited to one particular type ofconfiguration or implementation, such a configuration can be useful inthe case where the PCC 100 is implemented as a portable andself-contained unit. For example, the PCC 100 can be used in anautomobile or other situation wherein the PCC 100 is to function as astandalone unit. This would allow the user to send and receive messages,whether programmed, original, text, audio and/or video messages, to andfrom various locations.

The aforementioned components can be interconnected via suitableinterface circuitry. For example, data, including audio and video can berouted among the various components using a suitable communications busor other circuitry. Power connections (not shown) can be distributedfrom the power supply to the components of the PCC 100 as well.

FIG. 3 is a schematic diagram illustrating an exemplary embodiment ofthe patient door display. The icons 196 included in the patient doordisplay 195 can correspond to one or more of the icons of the PCCbuttons. Accordingly, upon activation of an icon, the corresponding iconof the patient door display 195 can be illuminated. The patient doordisplay 195 can provide personnel outside of the patient room with avisual indication of the patient's particular need. The patient doordisplay 195 functions separate from, and in addition to, any messagesprovided to the terminal located at the nurse station. The illuminatedicon provides an indication, not only that a patient has a particularneed, but also that the need has not been met. Once the patient need hasbeen addressed, the illuminated icon can be turned off by a member ofthe care-giver staff.

It should be appreciated that each icon of the PCC 100 need not beincluded in the patient door display 195. For example, different iconssuch as emergency icons or non-emergency icons can be shown dependingupon the patient and the patient's affliction. In one embodiment, thepatient door display 195 can be a video display such that any of the PCCbutton icons can be displayed or removed. Alternatively, the patientdoor display can be a mechanical illuminated sign wherein differentslip-in icon frames can be inserted to match the needs of a particularfacility, patient, or illness. A two-bed room can include a room numberindicator 197. This can notify care-giver staff which patient within aroom has initiated a request.

In operation, and referring to FIGS. 1-3, when a patient first checksinto a care-taking facility, the patient can provide pertinentinformation which can be entered into a data store such as a relationaldatabase or other patient management system which can be interlaced withthe invention disclosed herein. For example, the patient can specify anative or preferred language, preferred foods, any allergies to foods ormedication, as well as other pertinent information regarding designatedvisitors, form of payment, and the like.

Once in the patient room, the patient can operate the PCC to typemessages or activate buttons having pre-programmed messages. In one modeof operation, the messages can be displayed upon the patient's videodisplay to communicate with visitors or care-givers within the patient'sroom. In another mode of operation, messages can be routed to the nursestation or any other designated target location for which acorresponding button has been provided on the PCC. Correspondingly, eachtarget location can respond to the patient. Sent and/or receivedmessages, graphics, and text can be displayed upon the patient's videodisplay. Because the video display can display a picture, a televisionprogram, a movie, or some other form of entertainment, any text and/orgraphics generated by the present invention, whether from the PCC oranother station, can be overlaid upon the video display.

If the patient activates a nurse call button, a corresponding visualindicator such as an icon can be displayed at the nurse station. Thenurse can depress a button on the nurse keyboard which would givefeedback in the patient's room indicating that the message was received.This could be a double beep tone or an audible message sent back saying“nurse on the way”, “clean-up on the way”, “food on the way”, etc.,depending on which icon was activated. Alternatively, a general responsecan be used which can say “Your message was received at the nursestation and someone is on the way now.” Notably, if the patientspecified a language other than English as the default language, themessage can be translated to the desired language. The message can beprovided as text on the patient's video display or can be played aloud,i.e. as a recorded message or using text-to-speech. Still, nurses cancommunicate with the patient by typing messages which can be displayedupon the patient's video display, or verbally through a patient roomspeaker. Depending upon whether the patient can respond verbally, thepatient can provide a text response or a voice response. If a singlevideo display is used to service several patients within a single room,the monitor can indicate which patient a displayed message or visualidentifier is intended.

FIG. 4 is an illustration of an exemplary graphical user interface (GUI)400 of the patient's video display in accordance with the inventivearrangements disclosed herein. As shown in FIG. 4, a variety ofinformation can be displayed upon the patient video display. The displaycan provide several items of current information 405 including, but notlimited to, the room number, the patient's room telephone number, thedate, the time, as well as the temperature within the room and theoutside temperature. On duty staff information 410 can provide the nameof any attending nurse, physician, or other personnel. A picture 415 ofeach listed person can be included. Notably, the picture 415 provides anadded measure of security for patients as well as staff. Unauthorizedpersons attempting to gain access to a patient or a care-taking facilitycan be identified more easily by patients and staff alike. This can beparticularly useful with regard to patients who may require an addedsense of security or safety such as battered wives/husbands or victimsof other violent crimes or traumatic events.

An information box 425 can be included for listing any special notessuch as dietary requirements, allergies, standing requests, or otherinformation of note. GUI 400 can be, for example, a default screen whichcan be displayed when the patient activates the display or videomonitor. Alternatively, GUI 400 can be displayed upon activation of thePCC. For example, responsive to activation of one or more of the PCCbuttons, the PCC can generate a signal, either through the network orwirelessly, i.e. using radio frequency or infrared technology, toactivate the video display. Different backgrounds also can be displayedwithin GUI 400. For example, various scenic views can be selected by thepatient as background “wallpaper” for the video display. In oneembodiment of the present invention, patients can provide digitizedpictures which can be used as wallpaper for the video display.

FIG. 5 is another illustration of an exemplary GUI 500. GUI 500 depictsthe visitor center feature of the present invention. As shown, much ofthe information presented from GUI 400 also can be displayed within GUI500. GUI 500, however, can include a window 510 containing a live videofeed from the visitor center. While audio can be exchanged between thevisitor center and the patient room, in this embodiment of theinvention, a chat window 520 has been included. Using the chat function,a patient, who may not wish to be seen or heard, can interact with avisitor. As shown, the patient can view a live image of the visitor andcorrespond through text messages. In one embodiment of the invention,the text messages can be generated by a speech recognition engine ratherthan by manually typing the text. GUI 500 also can be used to playbackpre-recorded video and audio messages from visitors.

FIG. 6 is another illustration of an exemplary GUI 600 which can beprovided to the patient's video display. As shown in FIG. 6, icons610-640 have been illuminated or activated. In this embodiment of theinvention, as the user activates a particular button on the PCC, thecorresponding icon can appear on the patient's video display confirmingthat the patient has activated the proper button. Accordingly, thepatient can either leave the button activated as indicated by the icons610-640, or cancel one or more of the requests. In this case, thepatient has activated a button requesting assistance in using thebathroom as indicated by icon 610. Icon 620 can indicate that thepatient has requested the nurse. Icon 630 can indicate that the patientrequires medication. Icon 640 can indicate that the patient requiresassistance in washing. As mentioned, the icons also can be illuminatedon the patient's door display, which can be located inside or outside ofthe patient's room. In any case, the invention is not limited to theparticular icons used. Rather, any suitable color, symbol, picture, oralphanumeric character can be used as an indication of a particularservice or request.

FIG. 7 is another illustration of an exemplary GUI 700 depicting aninteraction between the nutrition center and the patient. As shown inFIG. 7, window 725 includes a message from the nutrition center askingthe patient to choose a main course for lunch. The patient can select amain course by pressing the number corresponding to the desiredselection. As mentioned, the selections offered to the patient can befiltered, and thereby individualized, in accordance with the informationprovided by the patient during check in. It should be appreciated thatduring check in, the patient can specify not only foods to which thepatient is allergic, but also preferred, favorite, or disliked foods.Accordingly, any foods that the patient has indicated that causeallergic reactions, or which the patient dislikes can be removed fromthe menu selections presented in window 705.

FIG. 8 is yet another illustration of an exemplary GUI 800 depicting thesituation where a care-giver has previously responded to a patientrequest and either the bathroom icon 805 has been reactivated or was notturned off. Accordingly, in window 810, the on duty nurse has sent atext message to the patient asking whether the patient still requiresassistance. A tone and/or a light, for example originating from the PCCor from another apparatus within the room, can notify the patient that amessage is waiting on the patient's monitor.
